Get a very cheap ph meter a yellow on for like 10$ is what I use and vinegar and baking soda is ph adjuster and in the kitchen cabinet

Lul, sorry if looks like i'm being too dramatic. I already killed like 7 seeds/seedlings so i'm just worried about losing another plant. :( Don't really know what i'm doing still.

I recommend you explore why that has happened. Seedlings are pretty durable, it’s later when all the hard stuff happens. If you have well draining soil and your water is a reasonable pH you should be able to keep a seedling alive. Key point - make sure those cups have drain holes and rocks or newspaper in the bottom. I hate starting in cups, they’re too short. Water bottles are better. But better yet is starting in the final container. Transplanting makes sense for houseplants, not for cannabis. That’s really stressful stuff and wastes a week of quality grow time recovering when it could be growing. You said in an earlier post that you don’t have money to be fussing with ph meters and up down… sorry to break the news, that’s baseline. If your water isn’t the right pH your plant isn’t going to get any nutrients. I wouldn’t be surprised if that’s why you’re killing plants. Lots of tap water is too high. If you don’t want to spend money blindly on testing stuff and chemicals, start by reaching out to your local public works department and say you would like to see their most recent water testing report because you are having some gardening issues and want to check whether water is the culprit. They’ll send it to you. And while it’s not as good as doing your own it will give you a sense a what issues you might have and what to watch out for… high pH, high alkalinity needs to be dealt with otherwise you’re going to keep killing plants.

I don't really have the money to spend on a ph meter or ph up and down chemicals to be doing all of that right now though. :\
I do think i may have overwatered it because i watered it to slight run off and the soil has stayed wet for like 4days now. I measured 300ml and gave it to the plant but i felt even then that i had overdone it.

I'll have to try and record the weights from now on because i'm really bad at remembering what things feel like after a while lul.

There are cheap strips they use to measure the chemicals in pools/hot tubs, which includes pH. It's like a litmus test, so you get a colour that you compare to a range provided by the strip manufactuer. While not very accurate, it is a cheap way of assessing you're at least in the ballpark. We had a facility, one of the first indoor ones, where we noticed the plants were really not doing very well at some point. Turned out to be a faulty pH sensor, which screwed up what the plants were getting and as a result they did poorly as pH was way off. No particular point to that last bit other than saying that pH is important:-)

It’s not ph man. fuck.

Update
I got a grow light for a smaller grow tent that i had laying around. It's a migro array 2, currently i have it 7-8" above the tallest plant.(manufacturers recommendation) I've left it on now for about 25 hrs. I'm trying to switch it's light cycle now that i can control it from 6am-8pm to 9pm-3pm.

The affected plant hasn't changed yet and still has only the one brown spot but i saw that another plant seems have developed something else on one of it's leafs as well. I'm not sure what it is but in person it doesn't look like a stain. It looks like the leaf lost it's color somehow. Would you guys consider this a cause for concern?

Since i'm trying to grow organic i'm really hoping that the soil will regulate the ph by itself. Appreciate the advice though, if i don't see any progress i plan to use the strips and vinegar/baking soda to adjust ph!

Yeah, from lurking around i've seen that many don't ph when running organic soil and i feel like the only the reason my other plants died was from not watering them correctly.

Yeah, i don't have things set up well yet but i plan to get some of those strips soon if things continue to get worse. Apprecite the advice mon.

I forgot to mention that exposing your plant to artificial light and then natural light can be ok if you make sure to keep the veg stage consistently in strong light for at least 18/6 (18 hours on/6 hours off) or 24 hours continuous in order to separate veg stage from the flowering stage of 12/12 (12 hours on 12 hours off.) You don't want to throw your plant in and out of veg and once you make the switch to flower you need to keep it consistent at 12/12 pretty much until the last few days of harvest. If the light timing is not consistent and goes back and forth from veg to flower, not only will it extend the time it will take to revert back to veg but can stress the plant and in some cases cause it to herm and produce male parts that will make a female plant produce seeds. Best to keep the lights up during the veg stage, first 3 months and then swap to flower stage 12/12. The 12 to 14 hours a day of light you mentioned should be very concerning... Good luck with your grow!

Now that i have a light i plan to keep it in it's tent for the most part and only give it sunlight whenever i'm able to but i'm really hoping nothing bad comes from it having such an inconsistent light schedule these last couple weeks! Thanks for taking the time to let me know brotha man.

Yeah. You def don’t need to ph. I think you are keeping them too wet. You really need to water the cup, and let it get as dry as you can before a wilt. A general way to gauge it, is when the cup feels like it is filled with styrofoam instead of dirt. It will get that light even before a wilt. Sometimes it can take 4-5 days for a proper dry out. Roots need air just as much as water. Def could be the cause of the washed put coloration of leaves too.

I was misting them at first trying to keep them as moist as possible, i'm not super sure why the ones i still have survived since i feel like i gave them all pretty much the same amount of water. I germinated 13 seeds, 11-12 (not sure really) sprouted and only 6 survived. The ones that didn't survive also had their shells on for like 5days until i removed them. I don't know if that may have effected them but i think the ones that survived, shed them quickly or i removed them before the other ones. The ones that died also grew very little from when they sprouted before they completely stopped growing.

Let them take their time, when you go snagging shells, the membrane will pull material out that will eventually be leaves and shit. It’s just gonna put the plant in stress mode immediately. You shouldn’t have to interfere in any way unless the seed has grown into a stem with the shell still on above dirt. Other wise let nature take its time, I know, it’s tough. But still. Spraying is not needed I. Any capacity for healthy seedlings, also, foliar treatment really doesn’t do anything nutrition wise, I only ever spray plants, when there are stowaways.

Yeah that's what i meant, the seedlings still had their shells on when they were about a inch tall above the dirt. I thought that it would fall off eventually since a couple of others did the same and shed them soon but they weren't able to. Only one of them that had it's shell stuck on them grew a little after i removed it but then it also stopped growing and did end up dying. Oh and i was misting mainly for humidity. Since people say that seedlings need high humidity to survive and my humidity where i live is not very high, i tried to spray them with water every 3-4 hours when i could the first week or so. Do you do anything for humidity whenever your growing seedlings?

Nope never will either. No domes
Any of that. Some folks swear by it,
But you really don’t need it. How low we taking?

That's pretty impressive, if you watch youtube grow channels most if not all really do swear by raising humidity for the seedling stage. Right now my plants are about a month old, i think i stunted them with my overwatering but at least i think they're still growing.

 

[mobshit]

I use a dome until they pop out. Take them out individually immediately when they break the surface. You don't want leggy seedlings from high humidity. I use rockwool so it's best not to shake the tray they are in or move them while they are trying to come out the surface. Usually the dome stays on to simulate a soak in water so they will soften the shell so it's easier for them to not get stuck on the head. I use 1% of 3% hydrogen peroxide. Comes out to 1 part peroxide to 2 parts ro or distilled water. it helps fresh or old seeds emerge faster. When I make my own seeds I have plenty so I remove the dome after the first seed sprouts. The rest would come soon afterwards. This more for keeping the top surface damp vs having to spray all the time to keep the top surface from drying out. When I start spraying I tend to overwater the medium.

It really depends for me, I run a lot of ladies on the regular, so sometimes, from a seedling starter to cup, maybe a week, then from a cup to a 1g or 3g a couple of weeks after. I’m never in a rush, so I almost always veg a lot longer than most folks who are in a hurry. And it depends on strain vigor the speed in which they get up potted. I’ll show a pic of some plants all born same day, same genetics in different Size pots for the sole purpose of slow rolling a grow to avoid bottleneck between grow rooms. It also makes the plants go nuts, the longer I keep them contained, by the time I do up pot they go nuts. But as a general answer to your question, every 2 to 3 weeks in full on veg, and 7ish days for a seedling.
My point is you can control a plant for a lot longer than most think……

 

[Captspaulding]

Even in flower if you want. It’s all about knowing how to water. And proper wet dry cycles couple with airflow.
